If I use a eGPU, will it increase the number of external monitor supported by my MacBook pro?

Hi,

In theory, yes. But make sure you check the specifications for the eGPU and what will the card support.

Have a look at this link from Apple.

“

An eGPU lets you do all this on your Mac:

• Accelerate apps that use Metal, OpenGL, and OpenCL
• ✅Connect additional external monitors and displays
• Use virtual reality headsets plugged into the eGPU
• Charge your MacBook Pro while using the eGPU
• Use an eGPU with your MacBook Pro while its built-in display is closed 
• Connect an eGPU while a user is logged in
• Connect more than one eGPU using the multiple Thunderbolt 3 (USB-C) ports on your Mac2
• Use the menu bar item  to safely disconnect the eGPU
• View the activity levels of built-in and external GPUs (Open Activity Monitor, then choose Window > GPU History.)

“

Hope this helps.

Yes, it will, but it costs on the order of US$1000. and provides full accelerated display capability.

If you only need a fairly slow display for pedestrian images like stock quotes or software listings, and do not need fine mouse-tracking on that display, there is a "simulated display" solution for US$50. It uses DiaplayLink technology and a DisplayLink chip in an external box.
